Considerations for KEMs #6

Closed OR13 closed 4 months ago

OR13 commented 4 months ago

KEMs are not defined for use in JOSE or COSE at the time we are writing the draft

We expect them to be defined soon, and we want to provide guidance that is consistent with both HPKE KEMs and non HPKE KEMs

DHKEM(P-384, HKDF-SHA384)

vs

In general KEMs fit where previously we would have seen ECDH-ES or ECDH-SS

Fully specified KEMS have a fixed KDF internalized

Polymorphic KEMS parameterize the KDF.
